    This sample showcases all predefined <b>GoJS</b> figures.
    This sample also makes use of <a href="../intro/highlighting.html">GoJS Highlighting</a> data bindings: Mouse-hover over a shape to see its name.
  </p>
  <p>
    You can specify a predefined geometry for a <a>Shape</a> by setting its <a>Shape.figure</a>.
  </p>
  <p>
    <strong>As of 2.0:</strong> In order to shrink the size of the GoJS library we no longer define most predefined figures in the library.
    Instead, you can find all of their definitions in the <a href="../extensions/Figures.js" target="_blank">Figures.js</a> file.
    You can load this file or simply load only those figures that you want to use by copying their definitions into your code.
  </p>
  <p>
    A number of very common figures remain predefined in version 2.0.
    The figures that remain in 2.0 are: <code>"Rectangle", "Square", "RoundedRectangle", "Border", "Ellipse", "Circle", "TriangleRight",
      "TriangleDown", "TriangleLeft", "TriangleUp", "Triangle", "Diamond", "LineH", "LineV", "BarH", "BarV", "MinusLine", "PlusLine", "XLine"</code>.
    These figures are filled green above, instead of pink.
  </p>
  <p>
    With GoJS you can also define your own custom shapes with SVG-like path syntax, see the <a href="icons.html">SVG icons</a>
    sample for examples or the <a href="../intro/geometry.html">Geometry Path Strings intro page</a> to learn more.
  </p>
  <p>
    For predefined arrowheads, see the <a href="arrowheads.html">Arrowheads</a> sample.
